HI 83224 COD Meter and Multiparameter Photometer
The HI 83224 is a multiparameter bench photometer with 15 methods for measurement of COD, chlorine, nitrate, nitrogen and phosphorus. This advanced meter features automatic recognition of bar coded samples, scanning each vial inserted into the vial holder and automatically identifying the sample method and range. This feature eliminates errors and simplifies the testing process.
The HI 83224 features a powerful interactive user support system that assists before, during and after analysis. On-screen tutorials guide through set-up, calibration and measurement while context sensitive help screens are available at a push of a button.
The instrument uses a new series of pre-dosed reagent vials for the 15 methods. Each reagent vial is bar coded with specific reagent information at the factory (with the exception of chlorine). This information is automatically scanned by the HI 83224 to assure that the vial and method are the same.
Key Features
- Measures Ammonia, Chlorine, COD, Nitrate, Nitrogen and Phosphorus
- Bar code reader detects the method and range automatically
- Three operation modes: Automatic, Semi-automatic and Manual
- Bar coded pre-dosed reagent vials
- On-screen step-by-step tutorial
- Logs up to 200 samples
- Context sensitive help screen at a touch of a button
- Selection of languages
- USB connection
- Graphic LCD
Operating Modes
The instrument has 3 operating modes. In Automatic mode, no user involvement is required in the method selection. In Semi-Automatic mode, user involvement is required when a different vial is identified related to the current method. In Manual mode, the user involvement is required at every level in the method selection.
Data Management
The HI 83224 can log and recall up to 200 different measurements. Stored data includes parameter, test results, sample number, lot number, instrument id, date and time. The bench photometer can be connected to a PC via USB. The HI 92000 Windows® compatible software (optional) aids users in managing data.
Vial Identification
Sample vials inserted into the HI 83224 are identified using bar codes. The bar code has 4 digits. The first 2 digits are for parameter identification and the second 2 digits are for reagent lot ID. For parameters that don't use a bar coded reagent, the vials supplied with the instrument should be used.
